UNITED STATES PATENT OFFICE.

HENRY E. PRIDMORE, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE MCCORMICK HARVESTING MACHINE COMPANY, OF SAME PLACE.

PLATFORM-FLAG FOR HARVESTERS.

SPECIFICATION forming part of Letters Patent No. 431,283, dated July 1, 1890. Application filed January 14, 1889. Renewed November 29, 1889. Serial No. 331,853. (No model.)

To all whom it may concern:

Be it known that I, HENRY E. PRIDMORE, a citizen of the United States, residing'at .Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Platform-Flags for Harvesters, of which the following is a specification.

This improvement has for its object the ad justment of the backboard or platform-flag,

as it is now called, toward or from the fingerbar while preserving its parallelism, and will be understood from the ensuing description.

The drawing represents a harvester-platform and portion of a harvester-elevator with a flag applied thereto according to myinven-- tlon.

A is the platform; B, the divider-girt; C, the finger-bar, and D the elevator.

In rear of the platform-conveyer, which is usually less in transverse sections than the width between the finger-bar and the rear sill E, I prefer to fill the space by an extension-board E over which the flag is adjusted; but, in case the conveyer is full width, of

2 5 course this board may be omitted.

F is the back-board or flag, having bolted to it two rearwardly-extending parallel arms or brackets G G, that reach to and in some adjustments may extend behind the rear sill.

3o Pivoted to the rear sill by clamping-bolts 7c, and also at one end to one of each of the brackets by bolts, which may also be clamping, are two equal swinging arms or radiusbars K, which, so long as they are held fast in 5 line with the sill or at an angle thereto by their clamps, will hold the flag in a determined adjustment; but whenever loosened so as to swing on their pivots will carry the brackets, and with them the flag, to the front 0 or the rear, as may be desired. \Vithout some to prevent one radius-arm from swinging farther than the other in the adjusting movement, and thereby holds the flag in strict parallelism.

I am aware that a patent has been granted to I. E. Arner on the 13th day of February, 1883, No. 272,016, in which the flag is mounted on swinging brackets, by means of which it is sought to obtain a parallel movement, and

such I do not claim; but

WVhat I do claim, and desire to secure by Letters Patent, is

1. The combination, with the harvesterplatform and the flag, of the radius-arms having heel-extensions, the bar connecting said heel-extensions, and devices for securing said radius-arms in fixed positions parallel with or at an angle to the rear sill.

2. The combination, with the harvesterplatform and the flag, of the parallel brackets extending rearwardly from said flag, the radius-arms having heel-extensions, the pivotal clamping-bolts whereby said arms are secured to the rear sill, and the bar connecting said heel-extensions, whereby the iiag is caused to move to front or rearin parallelism with said sill in its adjustments.
